The Effect of Pruning and Growth Regulator Treatments on Rose Plant Renewal1
Year: 1977
Type: article
Abstract: 6-(benzylamino)-9-(2-tetrahydropyran-yl)-9H-purine (PBA) in lanolin paste was applied to the greenhouse rose, Rosa hybrida L. cv. Red American Beauty, pruned in either a cutback or layback manner, and gibberellic acid (GA 3 ) sprays were applied after bud-break. PBA application generally increased bud-break on both layback and cutback-pruned plants. Gibberellic acid (GA 3 ) sprays did not improve growth of PBA-induced shoots. Layback-pruned plants developed a greater number of renewal canes (those reproductive stems that produced shoots of equal or greater basal stem diam after the first and second pinch) than cutback-pruned plants after growth regulator treatments.
